(UK - Tier 2 visa) I am a tier 2 visa holder and was overseas (out of UK) when I was dismissed from my job. I am still overseas, can I return to UK? [closed]

I am a Tier 2 visa holder employed by a professional services firm in London, UK.

I was dismissed from my job 2 weeks ago whilst out out of the UK (was overseas). I left the UK on 31 Nov 18, was dismissed on 13 Dec 18 and returning to UK on 1 Jan 2019. I need to return to the UK to pack up and send back my personal items in my rented apartment back my home country, and also say goodbye to my flatmate and friends.

My question is, can i reenter the UK with no issues? How should I explain my situation to the Immigration officer - should i tell him I am reentering as a tourist ( based on my nationality I don't need a tourist visa) or should i fully explain the situation that led to my current circumstance that I am/was a tier 2 visa holder which expires in 2021 but am no longer employed as I was dismissed whilst holidaying overseas?
